Journal of the American Chemical Society features on its supplementary cover the recently published research article “Single-Not Double-3D-Aromaticity in an Oxidized Closo Icosahedral Dodecaiodo-Dodecaborate Cluster”. 3D-aromatic molecules with (distorted) tetrahedral, octahedral, or spherical structures are much less common than typical 2D-aromatic species or even 2D-aromatic-in-3D systems. Closo boranes, [BnHn]2– (5 < n < 14) and carboranes are examples of compounds

Angewandte Chemie International Edition features on its front cover the recently published research article “Harnessing the Structure and Dynamics of the Squalene-Hopene Cyclase for (?)-Ambroxide Production”. Ambergris is a highly valued natural product in the fragrance industry and is also known as “floating gold” because of its biosynthesis in the intestines of sperm whales. Owing
The Organic Letters Journal features on its front cover the recently published research article “Enantioselective Molecular Recognition in a Flexible Self-Folding Cavitand” by Dr. Agustí Lledó and co-workers. A chiral and adaptable self-folding cavitand receptor based on calix[5]arene folds around the matched enantiomer of a chiral tetraalkylammonium guest, with the Els Encantats mountain (Catalan Pyrenees)
The Journal of Physical Organic Chemistry features on its front cover the recently published editorial “Excited-state aromaticity and antiaromaticity special issue”. The first fifty years have passed since Colin Baird’s pioneering paper in 1972 on the aromaticity and antiaromaticity. The cover is designed by Sílvia Escayola. The corresponding editorial was published recently: H. Ottosson, B. Durbeej and
The Chemistry A European Journal features on its front cover the recently published research article “The Insertion of EII and EIV Chlorides (E=Si, Ge) into the Si?Si Bond of Disilylene”. Reactions of silicon and germanium dichlorides L?ECl2 (E=Si, L=IPr; E=Ge, L=dioxane) with the phosphinoamidinato-supported disilylene ({?2(N,P)-NNP}Si)2 resulted in formal tetrylene insertions into the Si?Si bond. In the
Recently, Roger Monreal-Corona, Emili Besalú, Anna Pla-Quintana and Albert Poater reported in Organic & Biomolecular Chemistry on “Photoredox catalysis leading to triazolo-quinoxalinones at room temperature: selectivity of the rate determining step”. The interest in the fusion product of quinoxalinone skeletons and 1,2,3-triazole units has greatly increased in recent years since they are known to be
Recently, Daniel Bosch, Jun Wang and Lluís Blancafort reported in Chemical Science on “Fingerprint-based deep neural networks can model thermodynamic and optical properties of eumelanin DHI dimers”. Eumelanin is the biopolymer responsible for photoprotection in living beings and holds great promise as a smart biomaterial, but its detailed structure has not been characterized experimentally. Theoretical models
The Journal of Organic Chemistry features on its front cover the recently published research article “Successive Diels–Alder Cycloadditions of Cyclopentadiene to [10]CPP?C60: A Computational Study”. The cover art describes computationally the functionalization of the [10]CPP?C60 by cyclopentadiene through successive Diels–Alder cycloadditions reaching the hexakis adduct system. The graphics depict the successive cycloadditions over the [10]CPP?C60
Dual-Function Enzyme Catalysis for Enantioselective Carbon–Nitrogen Bond Formation This study reports a new biocatalytic platform for creating new carbon-nitrogen bonds in a very selective and efficient way, with applications in the pharmaceutical and industrial fields. The selective formation of these bonds is relevant for the synthesis of new bioactive and pharmacological compounds. To achieve this,
The journal Dalton Transaction features on its front cover the recently published research article “Catalysis of CO2 reduction by diazapyridinophane complexes of Fe, Co, and Ni: CO2 binding triggered by combined frontier MO associations involving a SOMO”, a collaboration between Kyushu University and IQCC. The previous study on the photochemical CO2 reduction into CO catalyzed by the
